Answer:
Step-by-step explanation:
1+sin²(a) +cos²(a) =2
note : for all a in R : sin²(a) +cos²(a) =1
so : 1+sin²(a) +cos²(a) = 1+1 =2
Answer:
95
Step-by-step explanation:
If you check, every Y number can be divided by X to get 95.
Answer:
The number of bleachers seat sold = 200
The number of end zone seats sold =200
The number of excellent seats sold =100
Step-by-step explanation:
Let there are bleachers seats =x
The number of zone seats =y
The number of excellent seats =z
So, we can set up equations for given sentences as
x+y+z= 500
20 x+30 y+40 z=14000
x=y
Substitute x as y into first two equations
y+y+z=500
20 y+30 y+40 z=14000
Simplify each
2 y+z=500
50 y+40 z= 14000
Multiply 2 y +z=500 by -40 to eliminate z terms when we add them.
-80 y-40 z=-20000
Add this with 50 y +40 z=14000, which gives
-30 y=-6000
Divide both sides by -30
y=200
Now, plug in y as 200 into any of the equations to find z.
2(200)+z=500
400+z =500
Subtract both sides 400.
z=100
Now, we know x=y
So, x=200
Answer:
$613.35
Step-by-step explanation:
As 1.45% of employee's pay check goes to the Medicare, so
Total pay of Kasey in next year=$42300
Amount to be paid to medicare=1.45% of Kasey^' s pay
=42300* 1.45/100
=42300* 145/10000
= 6133500/10000
=613.35
Kasey will have to pay $613.35 to Medicare.
